TECHNICAL FIELD

The present invention relates to a novel pyrimidine derivative having an antitumor activity, a cytostatic activity, and an inhibitory activity against a signal derived from Ras oncogene products.

BACKGROUND ART

The oncogene “ras” such as H-ras, K-ras, and N-ras is mutated and activated in many of neoplasms. The “Ras”, the products of ras oncogene, strongly concerns tumorigenesis caused by acceleration of cell cycle and induction of expression of many of genes associated with a malignant conversion such as a vascular endothelial growth factor and type-IV collagenase. Especially, it is found that there is highly frequent ras mutation in solid tumor such as pancreatic cancer (>80%), colon cancer (>40%), and lung cancer (>20%) which are difficult to be cured by using existing chemotherapeutics. Therefore, it is considered that Ras is one of the most important target molecules in the development of the chemotherapeutics against them.

A farnesyl-protein-transferase (FPT) inhibitor (FPTI) is known as chemotherapeutics of which target are Ras (WO95/13059, WO95/25086, WO95/25092, WO95/34535, U.S. Pat. No. 5,608,067, and JP-A-7-112930).

In the cells expressing activated Ras, the excess signals reach cell nucleus through some signaling pathways and some signal transmitter molecules such as MAPK (Mitogen Activated Protein Kinase) and PI3K (Phosphatidylinositol-3-Kinase). The signals activate the transcription factors such as AP1 (Activator Protein-1) and ETS (E26 transformation specific) in the cell nucleus and then they induce the expression of many genes related to malignant features through transcription activation element such as Ras Responsive Element (RRE). Therefore, it is possible to repress the malignant conversion of the cancer cells, when the signal transmission (a signal derived from ras oncogene products) is inhibited. Inhibitors of a signal derived from Ras oncogene products, of which basic structure is similar to that of the compounds of the present invention, are described in WO00/04014.

DISCLOSURE OF INVENTION

In the above situation, the inventors of the present invention have studied on the antitumor agent having an inhibitory activity against a signal derived from Ras oncogene products.

The activation of gene expression through RRE is in proportion to a signal derived from Ras and the signal can be measured by the amount of its expression. The inventors of the present invention artificially made cells having activated Ras wherein expression of firefly luciferase gene, reporter gene, is regulated by RRE and carried out a screening of the inhibitors taking luciferase activity shown by the cells as an index of signals through Ras. As a result, the inventors of the present invention found that a series of pyrimidine derivatives have a strong inhibitory activity against a signal derived from Ras oncogene products.

Test Example 1 Inhibitory effect against cellular signaling derived from Ras oncogene products

1) Establishment of Cell Lines Used in Assay

Based on the reporter plasmid (pGV-P (Toyo Ink, Japan)), in which luciferase gene was ligated to SV40-derived minimal promoter, we constructed a plasmid designated pRRE3-luc by inserting 3 copies of chemically synthesized oligonucleotides (Sequence: CAGGATATGACTCT, derived from mouse NVL-3 (M. A. Reddy et al.(1992)Mol. Endocrinol., 6, 1051)) into upstream of the promoter. v-ki-ras-transformed NIH373 cells (DT cells, provided by Dr. Makoto Noda (Kyoto Univ., School of medicine)) were transfected with this plasmid by liposome-mediated transfection and transfected cell lines stably incorporated and maintained each plasmid were obtained. We named pGV-P and pRRE3-transfected cell line as DT-C and DT-R, respectively and used in the assay described below.

2) Preparation of Samples

i) All the cell lines were cultured in Dulbecco's Modified Essential Medium (DMEM: 10% Fetal Calf Serum(FCS: Hyclone, USA)) including 60 mg/ml kanamycin (Meiji Seika, Japan) in humidified incubator under condition of 5% CO₂ at 37° C.

ii) DT-C and DT-R cells were seeded at 2500 cells/well into flat-bottom 96 well multiplate (Sumitomo bakelite) and incubated for 24 hours.

iii) Test compounds were prepared as 1 mg/ml DMSO solution.

iv) The solution of test compounds were added to the culture. Tested compounds are used at the concentration from 10 mg/ml to 0.51 ng/ml with 3-fold dilution.

v) After 24 hours, the culture supernatant was completely aspirated and 20 μl of cell-lysing solution (PGC-50 (Toyo Ink, Japan)) was added before cells were dried up. In order to lyse the cells completely, multiwell plates were left at room temperature for 10 to 30 min. The plates were wrapped up and stored at −20° C. till the day of measurement.

3) Measurement of Samples

i) Melt the samples by putting 96 well multiplate at 37° C. and add 90 μl/well 25 mM Tris (pH 7.5).

ii) Transfer 50 μl of the sample (110 μl) to the 96 well microplate (Microlite 1 (Dynatech)) for measurement.

iii) Measure the samples by the luminometer, LUMINOUS CT9000D (Dia-Yatron, Japan). We used Pickagene luminescence kit PGL2000 or LT2.0 (Toyo Ink, Japan) as enzyme substrates for luminescence measurement (50 μl/well).

4) Judgment of the Results

i) The luciferase activity of DT-C cells and DT-R cells were plotted in the graph where the relative activity and the compound concentration were expressed as Y-axis and X-axis, respectively. We judged by the degree of dissociation between the activities of DT-C cells and DT-R cells as an index.

ii) Concretely, efficacy of the compound was expressed by two values described below.

a) Among the points of concentration tested, the minimal concentration (Minimal Active Concentration: MAC), at which the activities of DT-C cells and DT-R cells dissociated, was shown as an index of efficacy of the compound.

b) Among the points of concentration tested, the concentration which is the nearest to 50% inhibition concentration at DT-C cells (IC50-C), was shown as an index of non-specific transcription-inhibitory effect or of cytotoxicity. In case of positive compounds, 50% inhibition concentration in DT-C cells which was higher than the active concentration was expressed as IC₅₀-C.

The results of the assay were shown in table 33.

Test Example 2 In vitro cell growth inhibition test Cells and MTT assay

Human squamous lung cancer RERF-RC-AI, human squamous lung cancer Ma44, human lung adenocarcinoma A549, human colon cancer HT29 and human pancreas cancer PANC-1 were used. All cell lines were cultured with Eagle's Modified Essential Medium (EMEM, supplemented with 10% fetal calf serum (FCS: Hyclone, USA) and 60 μg/ml Kanamycin (Meiji-seika, Japan) at 37° C. in a humidified incubator (5% CO₂). The cells were plated in 96-well microcultureplate. Twenty-four hours later, compound were added at the concentration from 10 μg/ml to 0.1 ng/ml with 2-fold dilution. MT7 assay was performed 4 days later and IC₅₀ values were determined. The results were shown in Table 34 in terms of concentration at ng/ml.
